Abstract (en)
An A/V equipment and a channel selecting method are disclosed, wherein the A/V equipment forms a wireless network by using information of each channel obtained by scanning each channel of a monitoring channel set to compute a predetermined parameter, and comparing the computed parameters to select an optimum channel. Consequently, the A/V equipment is configured to form a wireless network at a channel in which the wireless environment is the most satisfactory, thereby being enabled to satisfy a QoS requirement and to provide good quality of service, and to effectively distribute frequency resources under an environment, where the wireless equipment is mixed exists
